McPAC - AI (ELiza) Packet BBS for DOS by AC4X

Does anyone still have any copies of this 1980's vintage DOS packet program? I am looking for the MPC 4.03 version which I know is probably more of a wish than a reality. I have the 5.0 version, but was never able to get it to work (even back 20+ years ago). The earlier version worked just fine, but I didn't save the old disks. I am looking to set it up as part of a demo for how things were done before email (we did just fine). If anyone has a copy, I sure would appreciate getting a copy.
